While Grassley's Twitter account had been previously hacked, this time the use of the word "stupid" was his own. Aides say, "The Tweet is Sen. Grassley's. He is saying that it doesn't speak well of any constitutional law professor to not understand Marbury v Madison. The people understand the independence of the judiciary. So he thinks most Americans are smarter on the Constitution."

In a second Tweet, Grassley wrote,"Possibility of peace and freedom for Syria gets more remote as PresO plays along w the farce of Kofi Annans negotiatios (sic) there Barack wakeup."
